摘要
通过在植烟土壤中添加玉米秸秆、猪粪、未腐熟有机肥和腐熟有机肥4种有机物料,研究了其对烤烟不同生长时期土壤理化性质的影响。结果表明:(1)4种有机物料均能在一定程度上改善土壤环境,提高植烟土壤肥力;(2)不同有机肥对土壤理化性质的影响存在差别。与其它3种有机物料相比,施用腐熟有机肥在提高土壤肥力、改良酸性土壤、增强土壤保肥、供肥性能和缓冲能力方面具有较好的效果;秸秆对于提高土壤钾含量以及控制土壤碱解氮水平具有重要作用;猪粪在提高土壤磷含量方面效果较好。
The effect of physicochemical property of soil in different growth stages of flue-cured tobacco by using 4 organic matters（maize straw,pig manure,non-decomposted organic fertilizer and decomposted organic fertilizer）in the tobacco field were studied.The results indicated that：（1）the fertility and environment of soil planted flue-cured tobacco were improved to a certain extend by 4 organic matters;（2）The effects of different organic fertilizer on soil physicochemical properties were different.Compared with other organic matters,the effect of decomposted organic fertilizer in improving soil fertility,amending acid soil,enhancing the capacity of the soil nutrient preservation and supply and the soil buffer capacity was better;Maize straw played an important role in improving soil potassium content and controlling soil available nitrogen level;And the effect of pig manure in improving the soil phosphorus content was better than other organic matters.
